Here, we present a protocol for tracing genomic DNA (gDNA) contamination in RNA samples. The presented method utilizes primers specific for the internal transcribed spacer region (ITS) of ribosomal DNA (rDNA) genes. The method is suited for reliable and sensitive detection of DNA contamination in most eukaryotes and prokaryotes.

This protocol presents a workflow for sub-mm 2D visualization of multiple labile inorganic nutrient and contaminant solute species using diffusive gradients in thin films (DGT) combined with mass spectrometry imaging. Solute sampling and high-resolution chemical analysis are described in detail for quantitative mapping of solutes in the rhizosphere of terrestrial plants.

Plant Hormones

Plant hormones—or phytohormones—are chemical molecules that modulate one or more physiological processes of a plant. In animals, hormones are often produced in specific glands and circulated via the circulatory system. However, plants lack hormone-producing glands. Instead, plant hormones are often produced in regions of active growth, like the tips of roots and shoots. Additionally, even very low concentrations of plant hormones can have a profound effect on growth and development processes.
FAQs
Uptake depends on both contaminant behavior and plant conditions. Chemicals that dissolve readily may be more available for movement, whereas strong binding to soil can limit transfer into roots. Plant physiology also changes how water and nutrients move, so the same pollutant can show different distributions among plants or tissues.
Xylem transport links contaminant movement to water flow through the plant, while phloem transport connects movement with the distribution of sugars. These pathways can therefore expose different tissues to pollutants according to whether a chemical associates more closely with water movement or sugar transport. Distinguishing them helps explain accumulation in roots, shoots, or edible tissues.
Concentrations differ because contaminants can enter through roots, leaves, or stems and then follow distinct internal pathways. Solubility, soil binding, chemical properties, and plant physiology influence how far a pollutant moves after entry. Tracking these factors helps explain why contamination may remain concentrated in one tissue or reach parts of the plant relevant to food webs and human health.
An assessment can compare contaminant occurrence among roots, shoots, and edible tissues while considering the likely entry route and transport pathway. Interpreting those tissue patterns alongside solubility, soil binding, chemical properties, and plant physiology helps distinguish limited retention from broader movement. The resulting distribution supports predictions about environmental fate and possible exposure.
Transport information helps determine whether a plant is more likely to remove, stabilize, or transform pollutants in a contaminated environment. Researchers can use expected movement among roots, shoots, and other tissues to evaluate how a plant interacts with the pollutant. This supports selection and assessment of phytoremediation strategies rather than treating all plant-based cleanup responses as equivalent.
The distribution of pollutants through plant tissues helps connect contaminated environments with wider ecosystem consequences. If contaminants reach shoots or edible tissues, they may become relevant to food-web transfer and human exposure; if movement remains limited, risk patterns may differ. Evaluating these pathways therefore supports environmental fate analysis, ecosystem-health assessment, and interpretation of potential contamination routes.
